Hi everyone last question ... So had the idle hunting issue, when up to temperature it sits at 2000 minimum and hunts to 3000 constant up and down on idle.... Plan was to take it to work today and clean out the IACV... Hunted a little during the traffic lights etc but when I actually pulled up at work the revs settled back down to a thousand, and ticks over lovely... Fan kicks in and seems fine.... But.... Tried revving it a little and it won't go past 5000 rpm... Its like a limiter kicks in and it blew a load of black stuff out the exhaust ... Any help appreciated guys... Could this still be down to the IACV needing a clean or have I now got another issue? Just didn't want to take apart and clean if the idle has now settled and fine... Thanks all
